Pssst: the answer is low to rare: 33 cases of documented anaphylaxis in 25 million vaccines given.
The American Academy of Allergy, Asthma & Immunology sent me a copy of the new study, conducted by the Centers for Disease Control and Prevention (CDC) and published in the Journal of Allergy and Clinical Immunology.
Here’s the pertinent information:
“A recent study, conducted by the Centers for Disease Control and Prevention (CDC), assessed the relationship between vaccines and anaphylaxis and found the phenomenon rare in all age groups…
As such, Michael M. McNeil, MD, MPH, and colleagues searched the Vaccine Safety Datalink (VSD) databases to see who received one or more vaccines between January 1, 2009, through December 31, 2011….
Researchers examined records from a total of 17,606,500 visits for a total 25,173,965 vaccine doses administered. There were no deaths and only one patient was hospitalized. They found 33 confirmed cases of anaphylaxis after administration, a rate of only 1.31 cases per million vaccine doses."
They tracked all vaccines used, including two influenza vaccines. And still, only 33 cases of documented anaphylaxis in 25 million vaccines given.
